Hot dogs should have whatever the hell you want on them, including ketchup. Hmm, what else will the snobs lose sleep over? Maybe cheese? I haven't tried a hot dog with cheese, but already I see a variety of different ways of preparing a hot dog with cheese that could be interesting. May add onion AND cheese, and grill it. Yum. Hmm, but what type of cheese? Maybe some mozarella, maybe some queso fresco?
Oh, except pickle relish. Pickle relish doesn't belong on anything because its disgusting. I remember the first time I tried it, what a surprise that was. "Oh, this looks like a tasty salsa, maybe I will try i- OMG WTF DID I JUST EAT?!" *gag*
An abomination.
